I use Mint Linux (based on Ubuntu), but the above solution to get a root shell without password doesn’t work.

The system restarts, I use the arrow keys to choose “recovery” and type “e”, well I can edit the kernel-line and add “init=/bin/bash” but if I press ENTER, a new line is added. If I press ESC all changes are gone and in the menu “b” has no effect.

hi
i shared my computer with my room mate and both of us had a separate administrative user account.He has removed my administrative rights.Can i get the password of his account.
I have the root password

In Ubuntu 10.10 I went to very end of the line and added rw init=/bin/bash and now ubuntu seems to start up normally at first untill after the plymouth booting animation theres only a purple screen. When I logging through safe-mode theres a problem with the encryption manager. My home folder doesn’t get decrypted and because of that nautilus and gnome lack functionality.

this did not work for me says that root isn’t installed but in order to install anything i still need a password..when i try changing it using the passwd command says i still need a password to change it..followed the instructions to the T you gave above.

When i do this, passwd_space_user_space_password, I get to a “help desk”. It says : root@(none) :/# usage: passwd [options] [login]

Options :
And certain commands. I try to write my new password (not sure if its the timing to do it) and write reboot.
I get the “error” saying shutdown: Unable to send message: connection refused.
Can anyone help me from here? btw, 15 yrs old so this is pretty new. I have Vista (black screen of death before everything) so I try Ubuntu.
